Deconica semiinconspicua is a mushroom native to the state of Washington in the United States. The mushroom is small, rare, difficult to see and, according to Guzmán and Trappe (2005), stains blue where damaged.[2] However, Ramírez-Cruz et al. (2012) state that it is "without a really observable bluing reaction".[1] It was described as a psychoactive species of Psilocybe in section Semilanceatae, but Ramírez-Cruz et al. (2012) found that its macroscopic and microscopic morphological features and its DNA sequence, which Ramírez-Cruz et al. did not publish, were a better match for Deconica.[1] Ramírez-Cruz et al. (2012) also stated that it is very similar to Deconica montana.[1] It can be mistaken for Psilocybe silvatica and can be distinguished by its more conic cap, narrower spores and narrower cheilocystidia.[2]

Description
editCap
editThe cap is 7–12 mm and convex, becoming nearly plane in age. It is hygrophanous, has a smooth surface, and is olive black when moist, fading to brownish orange or dark reddish brown as it dries.[2]
Gills
editThe gills are Adnate light grayish brown at first, turning dark purple as the spores mature.[2]
Spores
editDeconica semiinconspicua spores are 8–10 x 5–7 μm, subovoid to ellipsoid, thick-walled, and yellowish brown to dark purple brown in deposit.[2]
Stipe
editThe stipe is 15–20 x 2 mm, hollow, has an equal width, and is white with whitish or brownish floccose scales, drying to a reddish brown. It stains blue near the base according to Guzmán and Trappe (2005).[2] Ramírez-Cruz et al. (2012) state that it is "without a really observable bluing reaction".[1]
Microscopic features
editThe basidia of Deconica semiinconspicua have four spores each. The cheilocystidia are sublageniform and 24–30 x 6–8 μm. No pleurocystidia have been observed. Clamp connections are present.
Habitat
editDeconica semiinconspicua is gregarious in small groups among shrubs on a creek bank.[2]
